headlight bars

How can I tell 29 29 headlight bars from 30 31 headlight bars?

 

[Bill G]

28/29 are flat between the headlight mounts. 30/31 are arched up in the center.

Also, the '28-29 headlight bars have a very much more pronounced steep angle bend where the ends curve down to meet the fenders. The arch difference is dramatic when the two bars are placed next to each other. You can spot the difference across the room, once you know what to look for.

Thank you both for the info. I have asked people selling them at swap meets and they didn't know. That is why I ask the experts. Again THANK YOU.
